Surface Effect Ships (SES)

marine

Vessels which benefit from an aerostatic force generated by a downward air current. See also hovercraft.

Surface energy

energy

Surface free energy or interfacial free energy or surface energy quantifies the disruption of intermolecular bonds that occurs when a surface is created.

Surface finish

energy

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).

Surface finish of hot rolled steel plates

marine

Steel plates must have a workmanlike finish and must be free from defects and imperfections which may impair their proper workability and use.

Surface preparation

marine

A process of surface cleaning before paint application. The surface preparation is of great importance for the quality and the durability of the coating.

Surface preparation grades

marine

The Swedish Standard Institution has published a very useful handbook entitled “Degrees of rust on steel surfaces and degrees for pretreatment of steel surfaces prior to application of rust preventing primers”.

Surface texture

energy

Surface texture is one of the important factors that control friction and transfer layer formation during sliding.

Surface wave

energy

In physics, a surface wave is a mechanical wave that propagates along the interface between differing media.

Surge protector

energy

A protection against voltage spikes in alternating currents electrical devices.

Surge tank

energy

A Surge tank is a water storage device used as a pressure neutralizer in hydropower water conveyance systems in order to dampen excess pressure variance.

Surveillance boat

marine

A fast boat used by coastguard service.

Survey

marine

Examination, testing and evaluation of the results and decision making.

Survey launches, tenders

marine

Small motor boats carried on board the hydrographic vessel for use in surveying operations.

Survey meter

energy

Survey meters in radiation protection are hand-held ionising radiation measurement instruments used to check such as personnel, equipment and the environment for radioactive contamination and ambient radiation.

Survey ship CAPELLA

marine
